SHOE LAST.

Application filed November 2, 1922. Serial No. 598,513.

To all whom t may concern.'

Be it known` that I, JOSHUA KING N ORTHRUP, a citizen of the UnitedStates,

residing at Ellicottville, in the county of` Cattaraugus and State ofNew York, have invented new and useful Improvements in Shoe Lasts, ofwhich the following is a specification.

This invention relates generally to lasts, but more particularly to a.sectional last whose heel part is detachable from its fore part.

One of the principal expenses in the manufacture of shoes is the cost ofthe lasts., one

last serving for a, comparatively few pairs of shoes, after which it isdiscarded for a new one. Still further expense is incurred in that it isnecessary to make new lasts to accord with the styles as they changefrom season to season. At the present time, these lasts are made of oneof our most valuable timbers of which the country is `fast beingstripped. y

One of the chief objects of this invention is the construction of aninexpensive last which is considerably more durable than those hithertoin use, thereby effecting a marked saving in the cost of shoemanufacture. 1 v

A further object is to provide improved means for detachably locking theparts of the last together.

ln the accompanying drawings:

Figure 1 is a longitudinal section of the improved last taken in theplane of line 1 1, Fig. 2. Figure 2 is a bottom plan view thereof.Figure 3 is a transverse section on line 3-3, Fig. 1. Figure 4 is anenlarged sectional view of the means for detachably holding the parts ofthe last together. Figure 5 is a horizontal section on line 5-5, Fig. 4.

Similar characters of reference indicate corresponding parts throughoutthe several views.

The invention is illustrated in connection with a two-part lastconsisting of a heel part and a fore part l1 which are slidably anddetaohabl connected along the substantially verticalyjoint-line 12.` Theadjoining faces of these arts are provided with oppositely-facingoulders 13, 14 to insure t e top and bottom portions of the heel sectionbeing iiush with the corresponding portions of the fore part sectionwhen said parts are assembled. ITo hold the sectionsagainst pullingapart lengthwise, one of them is provided with a'dovetail tongue 15which engages a corresponding groove 16 in the other part.

It will be noted. as shown in Figs. 1 and 'G0 4, that the joint-line 12inclines or slants1 forwardly from' the bottom to the top of the last.This construction permits the necessary shortening action of the last toenable the heel part to be removed from the shoe without affecting theIfore part. The last sections are preferably constructed of metal and lpropose to make the heel -part 10 of cast steell and the fore part 11 ofaluminum or like light metal or of hollow cast steel. The bot-tom ofsaid fore part is preferably provided with a recess or socket 17 forreceiving a renewable sole portion 18 of wood or similar material. Thelatter may be securely fastened to the lastsection by a screw 19 orother means. When this wooden sole portion becomes worn out from use, itis only necessary to substitute a new one for it, while the last-bodyitself can be used repeatedly, thus a'ording a saving of material andreducing the cost of the manufacture of shoes accordingly. B making thefore part of the lastof alumlnum, the same can be melted and recast intodierent shapes, to suit the changing styles of shoes, thus rendering itunnecessary to throw the last away. Practically no change in style isever made in the heel of the shoe, so that that section can be usedcontinuously with di'erently-shaped forepartv sections.

To hold thel parts of the last securely together and prevent anyrelative sliding movement thereof, a locking device iroctt as videdwhich is preferably constru follows:

The heel section 10 is provided with the usual jack-spindle socket 20and arranged at substantially right angles thereto, and opening into thelower end of said socket is a hole 21 which extends to the front face-of said section. Arranged in this hole is a the latter being sleeve 22and a bushing 23, located in front of the former and flush with the faceof the heel section. The fore-part 11 is provided with a socket 24 inaxial aline'- ment with the hole 21 and of the same diameter as the boreof the bushing 23. A springpressed locking bolt 25 is slidably mounted'fin the socket 24 and is adapted to project into thebushin 23, itsspring 26-normally holding said bo t in its locked or projected 'falleemleegeel space 3l eed el seul sockel', m lme with ly less allemposition 'for preventing relollye vertical dis placement of the lestsections., es shown im Fig. l.
